Digital News Report- The government has expanded its investigation into the cause of the Salmonella outbreak that has struck over 400 people in 43 states in the past few months. Five deaths have been linked to the outbreak. Last week, peanut butter became the top suspect in the outbreak after a five-pound jar of King Nut peanut butter was found to contain salmonella. King Nut issued a recall shortly after the link was discovered.
